While MP2RAGE has shown the potential to generate B1
insensitive T1 contrast over brain tissue at high
fields, the long scan time (> 8 mins) is undesirable
practically. However, the long TR (> 6s) is essential to
provide the large dynamic range of apparent T1
relaxation for dual MP2RAGE acquisitions. We propose
z-direcitonal accelated MP2RAGE, which provides the
increased flip angle with the similar dynamic recovery
as z-directionally non-accelearted MP2RAGE. Simulation
was conducted to optimize MP2RAGE paramenters and a
healthy subject was scanned with the optimized
parameters at 7T. The improved SNR and CNR with
z-direcitonal accelated MP2RAGE acclerate scan time
under 5 mins with isotropic 1mm3 voxel size.
